Module B1: "In Search of the Unknown," forms a complete adventure for use with Dungeons & Dragons Basic Set. It is especially designed as an instructional aid for beginning Dungeon Masters and players, specifically created to enable new Dungeon Masters to initiate play with a minimum of preparation.

In addition to descriptive and situational material, this module also includes special informational sections giving background history and legends; listings of possible monsters and treasures, and how to place them; a list of adventuring characters; tips on various aspects of play for the Dungeon Master; and helpful advice for starting players.

Product History

B1: "In Search of the Unknown," by Mike Carr, was originally released in November 1978 with a monochrome yellow cover. At the time, it was probably TSR's eighth adventure. It was also the first TSR adventure by someone other than Gary Gygax. However, its place in history as the first introductory adventure is much more important.

This adventure module was later revised and rereleased in additional editions in 1980 and 1981, eventually adopting TSR's full-color trade dress.

An Introductory Offer. The story of "Search" begins with the first Dungeons & Dragons Basic Set (1977), which was a reorganization of the rules from the original 3-book Dungeons & Dragons (1974) and Supplement I: Greyhawk (1975) produced by J. Eric Holmes. Following the publication of the Basic Set, TSR was looking for better introductory material to support it.

Enter TSR Games & Rule Editor Mike Carr, who saw the need for an introductory adventure that really taught GMs how to create and stock a dungeon. He offered to write such a product for TSR, who accepted. "In Search of the Unknown" was thus an introductory module for the introductory rule set - making it the ultimate introduction to the game.

An Introduction Inclusion. B1 was immediately packaged as part of the Basic Set - replacing geomorphs and monsters & treasure assortments, which had required GMs to be more comfortable creating dungeons on their own. It appeared as a part of the Holmes Basic Set from late 1978 through the end of 1979, at which time is was replaced by the better-known "B2: The Keep on the Borderlands" (1980).

An Introductory Adventure. The actual adventure leads off with advice about running adventures, but its introductory nature goes beyond that. Designer Mike Carr purposefully included a number of features that he thought players should expect in dungeons, like one-way secret doors, magic mouths, teleport doors, and more. Today, B1 is thus a great example of of the tropes of very early D&D dungeon design, but polished and detailed much better than the typical dungeons of the '70s.

The adventure features one other element of historical note: The rooms don't actually list what monsters and treasures they contain. Instead, GMs were expected to fill in those details themselves from lists at the end of the book. This design decision may have been intended to keep players on their toes (as there was concern in those early days that players might read modules they were going to play), or it may have been another lesson in how to create a dungeon. Regardless, the decision wouldn't be repeated again, with the exception of the recalled adventure "B3: Palace of the Silver Princess" (1981).

Basic or Advanced? When B1 was released, Basic D&D was not yet its own rule system, but rather an introductory set of rules that was intended to lead players on to the original D&D game or the AD&D game. The closeness of the Basic and Advanced lines in those days is revealed in B1's earliest printings, by the inclusion of a short section that explains how to convert the adventure to AD&D. That section was removed by the time the third printing appeared in 1979, and was the last attempt to overlap the two lines.

Afterward, the lines diverged with the release of the second-edition Dungeons & Dragons Basic Set (1981) by Tom Moldvay, which was by the time of its release considered its own game. That new Basic Set was also the impetus for the printing of the full-color covered edition of "In Search of the Unknown" in 1981.

About the Creators. Mike Carr was able to offer a uniquely introductory vision of D&D because he was only lightly involved with the game - his main interest being historical wargames, including his own Fight in the Skies (1966) / Dawn Patrol (1982). Though he edited later D&D adventures, B1 was Carr's only D&D writing; however, he later co-authored some Top Secret scenarios.

There's two files now. The one that starts with DDB has the color cover, the other the original two-tone cover. Otherwise I believe the text is the same. The one scanned from the older copy is a bit fuzzier and harder to read.

Can see just the two-tone cover here and bought thinking about the brownish one.

Same here. I only purchased it because I thought it was updated with a higher quality scan.

I downloaded this free on joining the DnD Classics website. I remember playing this with my friend Andrew in 81 or so. Its a good introductory adventure, but many of the rooms in the two levels of the dungeon are not filled. There is a list of monsters [...]

You know... I first played this back when I was a very young man. I later adapted it to work with AD&D 2nd Ed when I was DMing one of those campaigns... It worked well then, and it works well now! I recently adapted things AGAIN and made this [...]

This is my "go to" adventure anytime I want to start up a new group or game. It's a ritual for me, roll up characters and run them through the halls of the lost Castle of Quasqueton. I still have my copy that I bought all those years ago and [...]

I ported to 4E quickly and easily. It was no problem putting some basic monsters in the mod and then running it mostly on the fly. I loved the level of detail and exploration - my PCs had so much fun with the room of pools. It was a breath of fresh air [...]

These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.

Original electronic format

These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
